Each year the F1 circus descends upon Monaco for the most unique event of the season. Although there will be two more street races this year, the historic Monte Carlo layout would never be allowed if it were a new location seeking permission for a race today.
Thus the cars and their set ups are equally unique to the track. As ever the requirement is maximum grip; aerodynamically the need is for downforce, and drag is not such an issue.
On the mechanical side, softer tyres and suspension are employed to squeeze out more grip from the odd cambers and bumps that form the circuit.
This year, more teams have employed inerters (J-dampers) in their suspension to help equalise the unsettling effect of the tyres bouncing over the kerbs and bumps.
